What are three types of homologies that can be seen in organisms? Give example of each homologous?
Vaselesa [24]

Answer:

1. Iterative homology: e.g. antenna and leg of fiddler crab

2. Ontogenetic homology: e.g. radular teeth of veliger, feathers of chicken and hen

3. Di-polymorphic homology: e.g. white and brown feathers of hen races, chelae of male and female of fiddler crabs

4. Supraspecific: e.g. chelae of fiddler crab, chelae of lobster, feathers of hen and pheasant

How does the size of the soil particles impact<br> the soil's permeability (movement of water)?
Usimov [2.4K]

Answer:

Water moves by gravity into the open pore spaces in the soil, and the size of the soil particles and their spacing determines how much water can flow in. Wide pore spacing at the soil surface increases the rate of water infiltration, so coarse soils have a higher infiltration rate than fine soils.

How does soil particle size affect permeability?

But permeability is a different thing. It increases as particle size increases. By definition, permeability is a MEASURE OF EASE with which fluids will flow though a porous rock, soil or sediment. ... That means capillarity increase as particle sizes decreases.

Secondly, explain why energy is not just provided by the simple hydrolysis of ATP.
Nataliya [291]

Answer:

The exergonic reaction of hydrolysis of ATP must be coupled to an endergonic reaction to perform work or to power other reactions.

Explanation:

ATP (adenosin triphosphate) is hydrolized to give ADP and releases energy as follows:

ATP + H₂O ⇆ ADP + Pi + energy

The released energy itself is not used to power biochemical reaction. In order to power other reactions, ATP hydrolysis- a energetically favorable reaction- is coupled to another energetically disfavorable reaction. The linking or coupling is performed through a shared intermediate, which is often a phosphorilated molecule. For example, in the formation reaction of sucrose from glucose and fructose, an intermediate is formated by the transfer of a phosphate group (Pi) provided by ATP hydrolysis. Then, the phosphorilated intermediate (glucose-Pi)- wich is unstable- reacts with fructose in a spontaneous reaction to give sucrose.
